WHO IS AND WHO ISN'T?

"Now if anyone does not have the Spirit of Christ, he is not His."Romans 8.9

Who is saved? Who belongs to the Lord Jesus Christ? This verse leaves us without a shadow of a doubt. The good thing about these questions is that the Holy Spirit has already answered it deep inside those who are His, when He says: The Spirit Himself bears witness with our spirit that we are children of God. Romans 8.16
If you still have doubts, seek Him immediately.
